82 TENTHREDO BUFIVENTEIS. 



Allantus rufiventris, Ste., 111., vii, 65, 23. 



conspicuus, Ste., 1. c., 65, 24. 



laticinctus, Ste., 1. c., 65, 22. 



Black ; face, mouth, inner orbits of the eyes, tegulse, a line on the 

 pronotum, fifth apical joint of the antennae partly, sixth and seventh 

 wholly white ; the two apical joints fuscous ; pleura?, breast, abdomen 

 for the most part and legs reddish; posterior coxas, four posterior 

 femora above, and anterior slightly at the base, black. Front strongly 

 punctured, brassy, shining, slightly pubescent; mesonotum opaque, 

 slightly punctured ; pleurse strongly and roughly punctured ; breast 

 covered with a very short pile. Abdomen shining, smooth, brassy. 



The basal segment of the abdomen is always black, but the succeed- 

 ing segments vary in the intensity and amount of red which they 

 bear ; the pleurse are sometimes quite red, often there is only a faint 

 splash of that colour, the same being the case with the sternum ; the 

 white on the antennae varies in clearness, and the colour on the face 

 varies from white to reddish- white. The coloration of the coxse and 

 of the other parts of the legs varies also. The wings are almost 

 hyaline, but with a faint brownish tinge ; stigma pale testaceous. ? 

 and (?. 



Length 5 6 lines. 



This is a larger species than balteata. The tegulse 

 are white, the head and breast not so densely pubescent, 

 and more deeply punctured ; the pleurse are splashed 

 with red; the two last joints of antenna are fuscous, 

 the stigma pale testaceous, and the abdomen redder 

 and with a more bronzy tinge. 



The aberration with only the two basal segments of 

 the abdomen black is the T. conspicua, Kl. The 3 is 

 rare compared to the other sex. 



A tolerably common species, appearing in woods 

 during the latter part of June and in July. I have 

 taken it in the Glasgow districts, in Perthshire, Inver- 

 nessshire, Ross-shire, and Sutherlandshire ; have seen 

 specimens from Braemar, Berwickshire, and Dumfries- 

 shire, also from Newcastle (Bold), Norwich (Bridg- 

 man), London districts, Dorsetshire, Devonshire (Par- 

 fit t), Gloucester, and Worcester. 



On the Continent it occurs in Scandinavia, Germany, 

 Holland, France, and Italy.
